Non-wovens, that are cheaper to make and cleaner due to their disposable nature, are made with three or 4 layers. These disposable masks are sometimes made with two filter layers effective at filtering out particles akin to bacteria above 1 micron. The filtration degree of a mask, however, relies on the fiber, the best way it is manufactured, the web's structure, and the fiber's cross-sectional shape. Masks are made on a machine line that assembles the nonwovens from bobbins, ultrasonically welds the layers collectively, and stamps the masks with nose strips, ear loops, and different pieces.
The history of the surgical mask may be divided into three separate eras, the primary being the development and testing of the mask from 1905 to 1920, and the second being the period when the significance of the surgical mask was pressured and new masks had been developed, 1920-1940.

Moreover, the polymers utilized in creating masks are sometimes proprietary formulas.
